CVE-2025-1479 identifies a security vulnerability in Lenovo's Legion Space software, which is part of the Legion Go device ecosystem. The vulnerability is classified under CWE-489, indicating the presence of active debug code left enabled in the production software. Specifically, an open debug interface exists within the Legion Space software that could be accessed by a local attacker. This interface potentially allows the attacker to execute arbitrary code on the affected device. The vulnerability requires local access and low privileges to exploit, does not require user interaction, and affects confidentiality, integrity, and availability to a limited extent. The CVSS v4.0 base score is 4.8, reflecting a medium severity level. The attack vector is local (AV:L), with low attack complexity (AC:L), no authentication required (PR:L), and no user interaction (UI:N). The vulnerability impacts the Legion Space software on Legion Go devices, which are specialized gaming or high-performance portable computing devices from Lenovo. No known exploits are currently in the wild, and no patches have been published yet. The presence of active debug code in production software is a common security oversight that can expose internal interfaces and commands, potentially allowing attackers to bypass normal security controls and execute arbitrary code, leading to unauthorized system control or data compromise.

For European organizations, the impact of this vulnerability depends largely on the deployment of Lenovo Legion Go devices within their environment. Given that Legion Go devices are primarily consumer-focused portable gaming or high-performance devices, their presence in enterprise environments may be limited but not negligible, especially in sectors like media, design, or software development where high-performance portable devices are used. If exploited, the vulnerability could allow a local attacker with physical or local access to execute arbitrary code, potentially leading to unauthorized access to sensitive data, disruption of device functionality, or use of the device as a foothold for further network intrusion. The limited attack vector (local access required) reduces the risk of remote exploitation but does not eliminate insider threats or risks from compromised endpoints. Confidentiality, integrity, and availability could be compromised on affected devices, impacting user data and device reliability. Organizations relying on these devices for critical tasks should consider the risk, especially where devices are shared or used in less controlled environments.

To mitigate this vulnerability, organizations should first inventory their Lenovo Legion Go devices and assess their usage context. Since no official patch is currently available, immediate mitigation includes restricting physical and local access to these devices, enforcing strict user privilege management to prevent unauthorized local access, and monitoring for unusual local activity on affected devices. Lenovo or authorized vendors should be contacted for updates or patches. Additionally, organizations can implement endpoint detection and response (EDR) solutions to detect anomalous behavior indicative of exploitation attempts. Disabling or removing debug interfaces manually, if feasible and documented, can reduce exposure. For environments where these devices are critical, consider isolating them on segmented networks to limit potential lateral movement if compromised. User training to recognize and report suspicious device behavior is also recommended.
